This paper proposes a torque vectoring architecture for controlling the four electrical machines in a 4WD formula-type competition vehicle, including a new yaw-rate controller and an optimal torque distribution algorithm. Two yaw-rate controllers are designed based on different optimization methods, using an extended bicycle model validated with experimental data. Simulation results demonstrate the effectiveness of the proposed control scheme in terms of energy efficiency, cornering speed, and stability under high-demanding working conditions.
This paper addresses the design of a torque vectoring architecture to control the four electrical machines in a four-wheel-drive (4WD) formula-type competition vehicle. The scheme includes a new yaw-rate controller and a novel optimal torque distribution algorithm. Two yaw-rate controllers are proposed: one based on H-infinity optimal control and another based on linear parameter varying (LPV) system concepts. Both controllers are designed using an extended bicycle model validated with experimental data. Simulation results shown the effectiveness of the proposed overall control scheme in terms of energy efficiency, cornering speed and stability no matter the high-demanding working conditions. Such an effectiveness is quantitatively demonstrated by means of several key performance indicators chosen to ease the comparison of the proposed approach with respect to other reported works.
